UefiCpuPkg/PiSmmCpuDxeSmm: Remove PSD layout assumptions

Browse Source 
https://bugzilla.tianocore.org/show_bug.cgi?id=277

Remove dependency on layout of PROCESSOR_SMM_DESCRIPTOR
everywhere possible.  The only exception is the standard
SMI entry handler template that is included with the
PiSmmCpuDxeSmm module.  This allows an instance of the
SmmCpuFeaturesLib to provide alternate
PROCESSOR_SMM_DESCRIPTOR structure layouts.
